A woman in preterm labor at 30 weeks of gestation receives two 12 mg doses of betamethasone (Celestane) intramuscularly. The purpose of this pharmacologic treatment is to:
Reduce maternal and fetal tachycardia associated with terbutaline administration.
Suppress uterine contractions.
Stimulate fetal surfactant production.
Maintain adequate maternal respiratory effort and ventilation during magnesium sulfate therapy.
The Correct Answer is C
Betamethasone is a corticosteroid that enhances fetal lung maturity, which can help reduce the risk of respiratory distress syndrome and other complications in preterm infants. It does not reduce maternal and fetal tachycardia associated with terbutaline administration, suppress uterine contractions, or maintain maternal respiratory effort and ventilation during magnesium sulfate therapy.
